Concrete Yardage CalculatorHere is a concrete yardage calculator to help you determine how much concrete to order. Concrete is ordered by the cubic yard, but often, residential concrete projects are figured by inches and feet. Therefore you will need to go through these steps to convert to cubic yards: Step #1 - Figure the width, length and thickness of your concrete in terms of feet. To convert to feet, divide your inches by 12. For example, a 4 inch thick patio would be 1/3 (4 inches divided by 12 inches). Step #2 - Multiply the width in feet X length in feet X thickness in feet and divide by 27 (the number of cubic feet in a cubic yard). This number will yield the total amount of concrete you will need to order. For Example: Concrete for a 4 inch thick patio that is 10 X 20 square feet requires: 10 X 20 X 1/3 = 66.66 Divide 66.66 by 27 which = 2.46 cubic yards of concrete This formula does not allow for waste or variations in thickness. It is recommended that additional concrete be ordered in the amount of 5 to 10 percent to cover these variations. Usually it is sufficient to order a quarter of a cubic yard above what the project will actually need. So in the above example, round 2.46 to 2 1/2 and order 2 3/4 yards of concrete to account for waste. For curved concrete projects, make a square around the perimeter of your project and use those measurements for length and width. You may have a little bit of waste.
